Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 2-796642-4 is determined by the following critical parameters:

Primary Substitution Criteria:

• 24 positions with 0.197" (5.00mm) pitch or compatible 0.200" (5.08mm) pitch
• Male pins with 4-side shrouding
• Vertical through-hole mounting orientation
• Solder termination capability
• Voltage rating of 300 V (UL) or higher
• Current rating of 15 A (UL) or higher
• Operating temperature range encompassing -40°C to 110°C or equivalent

Substitute Categories:

Group 1: Direct Pitch Match (5.00mm)

• Phoenix Contact 1753877: Maintains 5.00mm pitch with 2-side shrouding (reduced shrouding vs. original)
• Current rating: 12 A (UL) - below original specification

Group 2: Compatible Pitch (5.08mm) with 4-Side Shrouding

• Assmann WSW Components A-TB500-OQ24CV: 5.08mm pitch, 4-side shrouding, 20 A (UL) current rating
• Assmann WSW Components A-TB508-OQ24CV: 5.08mm pitch, 4-side shrouding, 20 A (UL) current rating
• On Shore Technology Inc. EDSTLZ955/24: 5.08mm pitch, 4-side shrouding, solder mounting
• Amphenol PCD ELFH24250: 5.08mm pitch, 4-side shrouding, 15 A (UL) current rating

All substitute parts maintain 24 positions, vertical orientation, through-hole or solder mounting, 300 V (UL) voltage rating, and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: Assmann WSW Components A-TB500-OQ24CV

The A-TB500-OQ24CV provides the closest functional equivalence to the TE Connectivity 2-796642-4. This part maintains identical pitch (5.00mm), 24-position configuration, 4-side shrouding, vertical through-hole mounting, and solder termination. The current rating of 20 A (UL) exceeds the original 15 A specification, providing design margin. Operating temperature range extends to 115°C, encompassing the original -40°C to 110°C range. ROHS3 compliance and MSL 1 rating match the original part. Product status is active, ensuring long-term availability.

Secondary Recommendation: Amphenol PCD ELFH24250

The ELFH24250 offers equivalent electrical performance with 15 A (UL) current rating matching the original specification. The 5.08mm pitch represents a minor geometric variation from the 5.00mm original. Four-side shrouding, vertical through-hole mounting, and solder termination are maintained. Operating temperature range of -40°C to 105°C covers the critical lower temperature bound. ROHS3 compliance and active product status support procurement continuity.

Alternative Consideration: On Shore Technology Inc. EDSTLZ955/24

The EDSTLZ955/24 provides 4-side shrouding and 5.08mm pitch compatibility. However, mounting type is specified as solder rather than through-hole, and several electrical parameters are not specified. This part is suitable only when solder mounting is acceptable and when unspecified parameters do not conflict with application requirements.

Not Recommended: Phoenix Contact 1753877

The 1753877 features 2-side shrouding instead of 4-side, reducing mechanical protection. Current rating of 12 A (UL) is below the original 15 A specification. While pitch matches at 5.00mm, the reduced shrouding and lower current rating make this part suitable only for applications with relaxed mechanical and electrical requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1753877 be used as a direct replacement for the TE Connectivity 2-796642-4?

A: The 1753877 is not a direct replacement. While it maintains the 5.00mm pitch and 24-position configuration, it features 2-side shrouding instead of 4-side shrouding and has a current rating of 12 A (UL) versus the original 15 A (UL). Use this part only if application requirements permit reduced mechanical protection and lower current capacity.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: The pitch difference of 0.08mm (0.003") is a minor geometric variation. Parts with 5.08mm pitch (A-TB508-OQ24CV, A-TB500-OQ24CV, EDSTLZ955/24, ELFH24250) are compatible with applications designed for 5.00mm pitch in most standard PCB layouts. However, verify PCB hole spacing and connector receptacle compatibility before implementation.

Q: Are all substitute parts ROHS3 compliant?

A: Four of the five substitute parts are ROHS3 compliant (A-TB500-OQ24CV, A-TB508-OQ24CV, EDSTLZ955/24). The Phoenix Contact 1753877 and Amphenol PCD ELFH24250 are RoHS compliant but not specifically designated as ROHS3. For applications requiring ROHS3 certification, select from the four ROHS3-designated alternatives.

Q: What is the difference between through-hole and solder mounting types?

A: Through-hole mounting uses mechanical pins inserted into PCB holes and soldered in place, providing mechanical retention during assembly. Solder mounting relies solely on solder connection without mechanical pin retention. The original part and most substitutes use through-hole mounting. The EDSTLZ955/24 uses solder mounting, which may require different assembly procedures.

Q: Which substitute part offers the highest current rating?

A: Both Assmann WSW Components parts (A-TB500-OQ24CV and A-TB508-OQ24CV) offer 20 A (UL) current rating, exceeding the original 15 A specification. These parts provide the greatest design margin for current-carrying capacity.

Q: Is operating temperature range a critical factor in part selection?

A: Operating temperature range should be verified against application requirements. The original part operates from -40°C to 110°C. The Assmann parts extend to 115°C, providing additional margin at high temperatures. The EDSTLZ955/24 operates to only 105°C, and the ELFH24250 to 105°C. For applications requiring operation above 105°C, select the Assmann alternatives.

Q: Can the black-colored ELFH24250 be substituted for the green-colored original part?

A: Color difference does not affect electrical or mechanical function. The ELFH24250 is functionally equivalent despite its black housing versus the original green. Color selection depends on application requirements, assembly documentation, and visual identification needs.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. The part can be stored indefinitely without special moisture control measures and does not require baking before soldering. All listed parts carry MSL 1 rating, eliminating moisture-related procurement or handling constraints.
