Equivalent & Substitute Parts for Molex 0879370802

Part Overview

The Molex 0879370802 is an 8-position header spacer connector with 0.100" (2.54mm) pitch, designed for through-hole mounting with tin-plated contacts. This connector is part of the C-Grid 87937 series and maintains Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, lead time considerations, or design flexibility within the allowed parameter tolerances for rectangular connector applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0879370802 is determined by strict equivalence in the following critical parameters:

• Electrical Compatibility: 8 positions, 0.100" (2.54mm) pitch, single row configuration, tin contact finish
• Mechanical Compatibility: Through-hole mounting, solder termination, black color housing
• Regulatory Compliance: RoHS3 compliance, MSL 1 rating, EAR99 ECCN classification

The Samtec Inc. ZW-08-10-T-S-245-180 meets all substitution criteria. Dimensional variations in overall pin length, post mating length, stack height, and tail length are within acceptable tolerances for header spacer connectors and do not affect functional compatibility when used in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0879370802 and Samtec ZW-08-10-T-S-245-180 are Active products with full RoHS3 compliance and MSL 1 ratings, making them suitable for equivalent applications. Selection between these parts should be based on:

• PCB Layout Constraints: The Samtec part features a reduced stack height (0.245" vs. 0.433"), which may be advantageous in space-constrained designs.
• Mating Post Length: The Samtec part provides extended mating post length (0.405" vs. 0.149"), which may affect connector engagement depth in specific applications.
• Inventory Availability: Samtec ZW-08-10-T-S-245-180 shows higher inventory availability (1037 pcs vs. 685 pcs).
• Regulatory Compliance: Both parts meet identical compliance requirements (RoHS3, EAR99, HTSUS 8536.69.4040).

Frequently Asked Questions (FAQ)

Q: Can the Samtec ZW-08-10-T-S-245-180 be used as a direct replacement for the Molex 0879370802?

A: Yes, for applications where the dimensional variations in stack height, mating post length, and overall pin length do not conflict with PCB layout or mechanical assembly constraints. Both connectors share identical electrical specifications: 8 positions, 0.100" pitch, tin contact finish, and through-hole solder termination.

Q: What are the key differences between these two connectors?

A: The primary differences are dimensional. The Samtec part has a shorter stack height (0.245" vs. 0.433"), longer mating post (0.405" vs. 0.149"), and longer overall pin length (0.830" vs. 0.730"). These variations may affect PCB clearance, connector depth, and soldering characteristics.

Q: Are both connectors RoHS compliant?

A: Yes, both the Molex 0879370802 and Samtec ZW-08-10-T-S-245-180 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Which connector should I select for a new design?

A: Selection depends on specific PCB layout requirements. If stack height is a limiting factor, the Samtec part is preferable. If mating post length or overall pin length is critical to your application, verify compatibility with your connector housing specifications before selection.

Q: Do these connectors require different soldering profiles?

A: Both connectors use identical solder termination methods and tin contact finish. Standard through-hole soldering processes apply to both parts. Verify tail length compatibility with your PCB pad design.
