Substitute Part Grouping Explanation

Substitute parts for the 796697-4 terminal block header are grouped based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

Number of Positions: 4
Header Orientation: Vertical
Termination Style: Solder
Mounting Type: Through Hole
Material Flammability Rating: UL94 V-0
Insulation Height: 0.472" (12.00mm)

Secondary Compatibility Criteria:

Pitch: 0.197" (5.00mm) or 0.200" (5.08mm) — minor pitch variations within industry tolerance
Type: Header with Male Pins, Shrouded configuration
Voltage - UL: 300 V minimum
Current - UL: 10 A minimum

Substitution Logic:

Parts are classified into two categories:

Direct Substitutes — Identical pitch (0.197" / 5.00mm), matching shroud configuration (2 Side), active product status, and full electrical parameter alignment.
Similar Substitutes — Pitch variation (0.200" / 5.08mm), alternative shroud configurations (4 Side), or reduced current ratings (10-12 A vs. 15 A). These parts maintain core functional compatibility but require mechanical or electrical verification in specific applications.

Engineering Selection Recommendations

Direct Substitute — TE Connectivity AMP Connectors 1776138-4:

The 1776138-4 is the primary recommended substitute for the obsolete 796697-4. This part maintains identical electrical and mechanical specifications: 4 positions, 0.197" (5.00mm) pitch, vertical orientation, 2-side shrouded male pin header, solder termination, 15 A UL current rating, and 300 V UL voltage rating. The 1776138-4 carries active product status and RoHS Compliant certification, providing long-term supply assurance and regulatory compliance. The only difference is housing color (black vs. blue) and contact material (copper alloy vs. brass), which do not affect functional performance. This part is suitable for direct replacement in all applications.

Alternative Substitutes — Pitch 0.200" (5.08mm):

The Molex 0395310004, Phoenix Contact 1758034, and Phoenix Contact 1955400 offer functional equivalence with 0.200" (5.08mm) pitch spacing. These parts are suitable for applications where PCB layout accommodates the minor pitch variation. The Molex 0395310004 and Phoenix Contact 1758034 maintain 15 A and 12 A current ratings respectively, with active product status and RoHS compliance. The Phoenix Contact 1955400 operates at reduced current (10 A UL) and features a shorter contact tail length (0.102" / 2.60mm), requiring verification for specific board-level integration.

Alternative Substitutes — Pitch 0.197" (5.00mm):

The Phoenix Contact 1753479 and 1755260 provide pitch-matched alternatives with 12 A current ratings and active product status. These parts are suitable for applications where current requirements do not exceed 12 A. Both carry RoHS compliance certifications.

Shroud Configuration Variation — Amphenol PCD ELFH04250:

The ELFH04250 features 4-side shrouding (vs. 2-side on the main part) and 0.200" (5.08mm) pitch. This part maintains 15 A UL current rating and active product status with ROHS3 compliance. The reduced insulation height (0.319" / 8.10mm vs. 0.472" / 12.00mm) requires mechanical clearance verification. This part is suitable only where the enhanced shroud configuration and pitch variation are compatible with board design.

Non-Recommended Part — Amphenol Anytek TJ1131520000G:

The TJ1131520000G is not a suitable substitute. This part is an 11-position terminal block plug with female sockets, free-hanging orientation, and screw termination. It differs fundamentally in position count, connector type, mounting configuration, and termination method. This part was listed in the original substitute list but does not meet substitution criteria.

Frequently Asked Questions (FAQ)

Q: Can the 1776138-4 be used as a direct replacement for the 796697-4?

A: Yes. The 1776138-4 is electrically and mechanically equivalent to the 796697-4. Both parts feature 4 positions, 0.197" (5.00mm) pitch, vertical orientation, 2-side shrouded male pin headers, solder termination, 15 A UL current rating, and 300 V UL voltage rating. The 1776138-4 is active product status with RoHS compliance, making it the primary recommended substitute.

Q: What is the difference between 0.197" (5.00mm) and 0.200" (5.08mm) pitch?

A: The pitch difference is 0.003" (0.08mm). This variation is within industry tolerance for terminal block spacing but requires PCB layout verification. Parts with 0.200" (5.08mm) pitch cannot be directly substituted into designs requiring 0.197" (5.00mm) spacing without board redesign. Consult PCB documentation to confirm pitch compatibility.

Q: Why do some substitute parts have lower current ratings (10-12 A vs. 15 A)?

A: Current rating is determined by contact material, contact cross-section, and housing material thermal properties. Phoenix Contact COMBICON series parts are rated at 12 A per IEC standards, while the main part and certain substitutes are rated at 15 A per UL standards. Application current requirements must not exceed the substitute part's rated current. Verify load specifications before selection.

Q: What does "2-side shrouded" vs. "4-side shrouded" mean?

A: Shrouding refers to the plastic housing that surrounds the male pins. 2-side shrouding provides protection on two opposing sides, while 4-side shrouding provides complete enclosure on all four sides. The Amphenol PCD ELFH04250 features 4-side shrouding, offering enhanced protection but requiring verification of PCB clearance due to increased envelope dimensions.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts listed carry RoHS Compliant or ROHS3 Compliant certification. The original 796697-4 is marked "Not applicable" for RoHS status due to its obsolete classification. Substitutes provide regulatory compliance for new designs and ongoing system updates.

Q: What is the significance of contact tail length differences?

A: Contact tail length determines solder joint depth on the PCB. The main part features 0.138" (3.50mm) tail length. Substitutes range from 0.102" (2.60mm) to 0.154" (3.90mm). Longer tail lengths provide greater solder joint strength and mechanical stability. Shorter tail lengths (such as the Phoenix Contact 1955400 at 0.102") may require PCB design adjustment to ensure adequate solder fillet formation.

Q: Can I use the Amphenol Anytek TJ1131520000G as a substitute?

A: No. The TJ1131520000G is fundamentally incompatible. It is an 11-position terminal block plug with female sockets, free-hanging orientation, and screw termination. The main part is a 4-position header with male pins, vertical through-hole mounting, and solder termination. These parts serve different connector functions and cannot be interchanged.

Q: What is the difference between "Buchanan" and "COMBICON" series?

A: These are manufacturer-specific product series designations. The main part belongs to TE Connectivity's Buchanan series, while several substitutes belong to Phoenix Contact's COMBICON series. Series designation does not affect electrical or mechanical compatibility; it is a manufacturer classification system. Compatibility is determined by the electrical and mechanical parameters listed in the comparison table.

Q: Should I select a substitute based on color?

A: No. Color is a cosmetic attribute and does not affect electrical or mechanical function. The main part is blue, while most substitutes are black or green. Color selection should not be a primary criterion for substitution decisions. Focus on electrical ratings, pitch, position count, and mounting configuration.

Q: What is Moisture Sensitivity Level (MSL)?

A: MSL indicates the component's sensitivity to moisture absorption during storage and handling. All listed parts carry MSL 1 (Unlimited), meaning they have unlimited shelf life and do not require special moisture-controlled storage conditions. This specification does not affect substitution compatibility.
