Molex 0879370502 Equivalent & Substitute Parts

Part Overview

The Molex 0879370502 is a 5-position header spacer connector with 0.100" (2.54mm) pitch, designed for through-hole mounting applications. This connector features tin-plated contacts and is part of the C-Grid 87937 series. The product maintains active status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0879370502 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: 5-position configuration with 0.100" (2.54mm) pitch spacing
• Mechanical Compatibility: Through-hole mounting with solder termination
• Contact Properties: Tin-plated mating posts
• Physical Dimensions: Overall pin length of 0.730" (18.542mm) and stack height within acceptable tolerance
• Regulatory Compliance: RoHS3 compliance and MSL 1 rating

The Samtec Inc. ZW-05-09-T-S-430-150-LL meets these criteria with minor dimensional variations within engineering tolerance for stack height (0.430" vs. 0.433") and mating post length (0.150" vs. 0.149").

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0879370502 and Samtec ZW-05-09-T-S-430-150-LL maintain active product status with full RoHS3 compliance and MSL 1 ratings. Selection between these parts is based on availability, lead time, and design-specific requirements. The Samtec part features kinked pin termination in addition to solder termination, providing enhanced mechanical retention. Dimensional variations in stack height and mating post length are within standard engineering tolerances for this connector category and do not affect functional compatibility in standard through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Can the Samtec ZW-05-09-T-S-430-150-LL be used as a direct replacement for the Molex 0879370502?

A: Yes. Both connectors share identical electrical specifications (5 positions, 0.100" pitch), mounting method (through-hole), contact finish (tin), and regulatory compliance (RoHS3, MSL 1). Dimensional differences in stack height and mating post length are within acceptable engineering tolerance for PCB-mounted applications.

Q: What is the significance of the kinked pin termination on the Samtec part?

A: Kinked pin termination provides additional mechanical retention during PCB assembly and soldering processes. This feature does not affect electrical performance or compatibility with standard 0.100" pitch receptacles.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are RoHS3 compliant, carry MSL 1 (unlimited) moisture sensitivity ratings, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching position count (5), pitch spacing (0.100"), mounting type (through-hole), termination method (solder), contact finish (tin), and regulatory compliance status. Dimensional variations within standard tolerances do not prevent substitution.

Q: Should I verify compatibility before implementing a substitution?

A: Confirm that your PCB design accommodates the specified overall pin length (0.730") and stack height (0.430"–0.433"). Both parts are designed for standard 0.100" pitch receptacles and require no additional design modifications.
