TE Connectivity AMP Connectors 2-796867-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 2-796867-1 is a 21-position terminal block header with male pins, shrouded on four sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component belongs to the Buchanan series and is classified as obsolete. The part operates at 15 A (UL) and 300 V (UL) with an operating temperature range of -40°C to 110°C.

Due to the obsolete product status of the 2-796867-1, identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. Substitute parts must maintain electrical and mechanical compatibility while meeting the same functional specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-796867-1 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• 21-position configuration
• 0.200" (5.08mm) pitch spacing
• 15 A current rating (UL)
• 300 V voltage rating (UL)
• Tin contact mating finish

Mechanical Compatibility:

• Vertical header orientation
• Male pins with 4-side shrouding
• Through-hole solder termination
• Mating flange feature
• UL94 V-0 flammability rating

Environmental Compliance:

• MSL 1 (Unlimited) moisture sensitivity
• Operating temperature range compatibility

The substitute part ELFH21250E from Amphenol PCD meets all critical electrical and mechanical parameters. While minor variations exist in housing material (PBT versus PA66), insulation height, and operating temperature maximum (105°C versus 110°C), the part maintains functional equivalence for the specified application requirements.

Engineering Selection Recommendations

The ELFH21250E from Amphenol PCD is the direct functional equivalent for the obsolete TE Connectivity 2-796867-1. Selection of this substitute is based on the following engineering criteria:

Product Status Alignment: The ELFH21250E maintains active product status, ensuring ongoing availability and supply chain support compared to the obsolete 2-796867-1.

Electrical Equivalence: Both parts maintain identical current (15 A UL) and voltage (300 V UL) ratings, ensuring safe operation within the same circuit parameters.

Mechanical Compatibility: Both parts feature 21-position, 0.200" (5.08mm) pitch vertical through-hole headers with male pins and 4-side shrouding, supporting direct PCB footprint compatibility.

Compliance Certifications: Both parts carry UL94 V-0 flammability ratings and meet RoHS compliance requirements. ECCN and HTSUS classifications are identical, supporting regulatory and trade documentation consistency.

Environmental Specifications: Both parts operate across the -40°C to 105°C range (ELFH21250E) within the specified -40°C to 110°C envelope of the original part, with MSL 1 (Unlimited) moisture sensitivity classification.

Material Considerations: The ELFH21250E uses PBT housing material and brass contacts compared to PA66 nylon and copper alloy in the original part. Both material sets meet UL94 V-0 requirements and support equivalent electrical performance in the specified application.

Frequently Asked Questions (FAQ)

Q: Can the ELFH21250E be used as a direct replacement for the 2-796867-1 in existing designs?

A: Yes. The ELFH21250E maintains electrical and mechanical equivalence across all critical parameters: 21-position configuration, 0.200" (5.08mm) pitch, 15 A (UL) current rating, 300 V (UL) voltage rating, vertical through-hole solder termination, and 4-side shrouded male pin design. PCB footprint compatibility is maintained.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Product status—ELFH21250E is active while 2-796867-1 is obsolete; (2) Housing material—PBT (ELFH21250E) versus PA66 nylon (2-796867-1); (3) Contact material—Brass (ELFH21250E) versus Copper Alloy (2-796867-1); (4) Insulation height—0.319" (8.10mm) versus 0.472" (12.00mm); (5) Maximum operating temperature—105°C versus 110°C. These differences do not affect functional equivalence for standard applications.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both parts carry UL94 V-0 flammability ratings, RoHS compliance, and identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Regulatory and trade documentation requirements are maintained.

Q: Does the difference in insulation height affect PCB layout?

A: The ELFH21250E has a lower insulation height (0.319" versus 0.472"). This difference must be evaluated against specific PCB clearance requirements and component spacing in the target application. The reduced height may provide design flexibility in space-constrained layouts.

Q: What is the impact of different housing materials on performance?

A: Both PA66 nylon and PBT materials meet UL94 V-0 flammability requirements and support equivalent electrical performance. PBT offers enhanced chemical resistance and dimensional stability. Material selection does not affect electrical function within the specified voltage and current parameters.

Q: Is the operating temperature difference significant?

A: The ELFH21250E operates to 105°C maximum compared to 110°C for the 2-796867-1. For applications operating below 105°C, this difference is not significant. Applications requiring operation above 105°C must retain the original 2-796867-1 or identify alternative solutions.

Q: What packaging is available for the ELFH21250E?

A: The ELFH21250E is supplied in bulk packaging with 1036 pieces currently in stock, compared to the 2-796867-1 which is obsolete with 765 pieces remaining in inventory.
