Substitute Part Grouping Explanation

Substitution eligibility for the 79849-136 is determined by strict alignment with the following core parameters:

Connector type: Header with male pin contact
Position count: 36 positions
Pitch: 0.100" (2.54mm)
Mounting: Through hole with solder termination
Fastening: Push-pull mechanism
Contact shape: Square
Insulation height: 0.100" (2.54mm)
Flammability: UL94 V-0

All four substitute parts meet these mandatory criteria. Variations in contact length, contact finish composition, and operating temperature ranges are secondary parameters that do not prevent functional substitution but may affect application suitability based on specific design requirements.

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the 79849-136 based on core electrical and mechanical parameters. Selection should be guided by the following factors:

Product Status: The 79849-136 is obsolete. All substitute parts are active products with ongoing manufacturer support and availability.

Compliance: The original part is RoHS non-compliant. Substitutes 929705-06-36-I, PBC36SFAN, PEC36SFAN, and PEC36SFCN are all RoHS compliant (RoHS or ROHS3), making them suitable for applications requiring regulatory compliance.

Contact Finish Considerations: The original part specifies gold or gold GXT™ finish on mating contacts. Substitute 929705-06-36-I maintains gold finish on both mating and post contacts. Sullins parts PBC36SFAN, PEC36SFAN, and PEC36SFCN use tin finish on mating and post contacts, which is acceptable for standard applications but differs from the original specification.

Contact Length Variations: The 929705-06-36-I features extended post length (0.710"), suitable for applications requiring deeper PCB penetration. The Sullins parts maintain post lengths closer to the original specification (0.120" to 0.320"), providing better dimensional compatibility with existing board layouts.

Operating Temperature Range: Sullins parts (PBC36SFAN, PEC36SFAN, PEC36SFCN) support -65°C to 125°C, exceeding the 3M part's -40°C to 105°C range and providing broader environmental capability.

Current Rating: Sullins parts are rated for 3A, compared to 3M's 2.5A rating, offering higher current capacity.

Frequently Asked Questions (FAQ)

Q: Can the 929705-06-36-I be used as a direct replacement for the 79849-136?

A: Yes. The 929705-06-36-I meets all core substitution criteria: 36-position header, 0.100" pitch, through-hole solder termination, push-pull fastening, and square contacts. The extended post length (0.710") differs from the original (0.120"), which may require PCB layout verification for applications with space constraints.

Q: What is the difference between the Sullins PBC36SFAN and PEC36SFAN?

A: Both parts are functionally equivalent with identical core specifications. The primary difference is contact finish: PBC36SFAN uses gold mating finish with tin post finish, while PEC36SFAN uses tin finish on both mating and post contacts. Both support -65°C to 125°C operating temperature and 3A current rating.

Q: How does PEC36SFCN differ from PEC36SFAN?

A: Both are Sullins parts with tin contact finish and identical electrical ratings. The key difference is post length: PEC36SFCN has 0.320" post length compared to PEC36SFAN's 0.120", resulting in overall contact lengths of 0.738" and 0.538" respectively. Selection depends on PCB thickness and mounting depth requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts (929705-06-36-I, PBC36SFAN, PEC36SFAN, PEC36SFCN) are RoHS compliant, whereas the original 79849-136 is RoHS non-compliant. This makes substitutes mandatory for applications subject to RoHS regulations.

Q: Which substitute offers the closest dimensional match to the original 79849-136?

A: PBC36SFAN and PEC36SFAN provide the closest overall contact length match (0.538" vs. original 0.620"), making them optimal for designs with existing PCB layouts and mechanical constraints.

Q: Can these parts be used interchangeably in the same application?

A: Core electrical and mechanical compatibility is maintained across all substitutes. However, contact finish (gold vs. tin), post length variations, and operating temperature ranges should be evaluated against specific application requirements before final selection.
