Substitute Part Grouping Explanation

Substitute parts for the 78269-172 are qualified based on the following critical parameters that must match or remain compatible:

Connector type (Header with breakaway capability acceptable)
Contact type (Male Pin)
Number of positions (72)
Number of rows (2)
Pitch spacing (0.100" / 2.54mm mating and row spacing)
Mounting type (Through Hole)
Termination method (Solder)
Fastening type (Push-Pull)
Contact shape (Square)
Insulation height (0.100" / 2.54mm)
Material flammability rating (UL94 V-0)
Insulation color (Black)

Substitute parts from Sullins Connector Solutions (PBC36 and PEC36 series) meet these core requirements. Variations in contact length dimensions (mating and post lengths) and contact finish specifications are permitted as these do not affect the fundamental electrical or mechanical compatibility for board-to-board interconnection applications.

Engineering Selection Recommendations

All substitute parts listed are active products from Sullins Connector Solutions and maintain electrical and mechanical compatibility with the 78269-172 for board-to-board interconnection applications. The primary distinction between substitute options relates to contact length dimensions, which determine the overall connector height and post extension length for PCB penetration depth.

Sullins PBC36 series parts feature gold-plated mating contacts with tin-plated posts. Sullins PEC36 series parts feature tin-plated mating and post contacts. Both series are ROHS3 compliant, whereas the original 78269-172 is RoHS non-compliant. All substitute parts maintain UL94 V-0 flammability rating and operate across the -65°C to 125°C temperature range with 3A current rating per contact.

Selection among substitute variants should be based on required post length for PCB mounting depth: PBC36DAAN and PEC36DAAN provide 0.120" (3.05mm) post length; PBC36DABN and PEC36DABN provide 0.230" (5.84mm) post length; PBC36DACN provides 0.320" (8.13mm) post length; PBC36DAFN provides 0.620" (15.75mm) post length; PBC36DAHN provides 0.820" (20.83mm) post length.

Frequently Asked Questions (FAQ)

Q: Can PBC36 and PEC36 series parts directly replace the 78269-172?

A: Yes. Both series maintain the same 72-position, 2-row configuration with 0.100" (2.54mm) pitch spacing, through-hole solder termination, and push-pull fastening. The primary difference is contact finish specification and post length options. Selection depends on PCB mounting depth requirements.

Q: What is the difference between PBC36 and PEC36 series?

A: PBC36 series features gold-plated mating contacts with tin-plated posts. PEC36 series features tin-plated mating and post contacts. Both maintain equivalent electrical performance and mechanical compatibility. Contact finish selection depends on application requirements and solderability preferences.

Q: How do I select the correct post length variant?

A: Post length determines how far the connector extends into the PCB. PBC36DAAN/PEC36DAAN (0.120" post) suit standard PCB thicknesses. PBC36DABN/PEC36DABN (0.230" post) accommodate thicker PCBs or stacked configurations. PBC36DACN (0.320" post), PBC36DAFN (0.620" post), and PBC36DAHN (0.820" post) provide extended penetration for applications requiring deeper board engagement or additional clearance below the PCB.

Q: Are all substitute parts RoHS compliant?

A: All Sullins substitute parts (PBC36 and PEC36 series) are ROHS3 compliant. The original 78269-172 is RoHS non-compliant. If RoHS compliance is required for your application, substitute parts satisfy this requirement.

Q: What is the current rating for these connectors?

A: All substitute parts are rated for 3A per contact. The original 78269-172 does not specify a current rating in available documentation.

Q: Do these connectors support breakaway functionality?

A: Sullins PBC36 and PEC36 series are specified as Header, Breakaway type connectors, allowing individual position separation if required. The original 78269-172 is specified as unshrouded header without breakaway designation.

Q: What is the operating temperature range?

A: All Sullins substitute parts operate across -65°C to 125°C. The original 78269-172 does not specify an operating temperature range in available documentation.
