Molex 0872673250 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0872673250 is a surface mount rectangular connector header from the Milli-Grid 87267 series, designed for board-to-cable/wire applications with 32 positions arranged in 2 rows at 0.079" (2.00mm) pitch. This component features male pins with gold-plated mating contacts and tin-lead plated posts, housed in a black polyamide insulation body with board guide features.

The 0872673250 carries an obsolete product status. Identifying functionally equivalent active alternatives is essential for ongoing design support, procurement continuity, and new production builds where this legacy component is no longer readily available through standard distribution channels.

Substitute Part Grouping Explanation

The Molex 0877593250 qualifies as a direct functional substitute for the 0872673250 based on alignment across all critical electrical and mechanical parameters that govern connector interchangeability:

Matching Parameters:

• Connector type (Header with breakaway capability)
• Contact type (Male Pin)
• Position count and row configuration (32 positions, 2 rows)
• Pitch specifications (0.079" mating pitch, 0.079" row spacing)
• Surface mount termination method
• Mating contact length (0.150")
• Insulation height (0.059")
• Contact shape (Square)
• Mating contact finish (Gold at 15.0µin thickness)
• Contact material (Phosphor Bronze)
• Unshrouded design with board guide
• Push-pull fastening
• UL94 V-0 flammability rating
• MSL 1 rating
• Application domains (Automotive, General Purpose, Telecommunications)

Distinguishing Characteristics: The 0877593250 operates under active product status with ROHS3 compliance, whereas the 0872673250 is obsolete and RoHS non-compliant. The substitute features thermoplastic insulation material versus polyamide in the original, and tin post finish versus tin-lead. These differences do not affect functional compatibility for standard board-to-board or cable interconnect applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0877593250 is the appropriate substitute for the obsolete 0872673250 in new designs and production transitions. The substitute maintains full mechanical and electrical compatibility across all specified mating and mounting parameters.

The 0877593250 carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment with current manufacturing standards. The transition from tin-lead to tin post finish and polyamide to thermoplastic insulation material reflects modern material science practices and does not compromise functional performance in the specified application domains of automotive, general purpose, and telecommunications use.

For existing designs currently using the 0872673250, the 0877593250 provides a direct drop-in replacement without requiring PCB layout modifications or connector interface redesign, provided that the design does not explicitly depend on the tin-lead post finish or polyamide insulation properties.

Frequently Asked Questions (FAQ)

Q: Can the 0877593250 be used as a direct replacement for the 0872673250 without PCB redesign?

A: Yes. Both connectors share identical pitch specifications (0.079" mating and row spacing), mounting type (surface mount), contact length (0.150"), insulation height (0.059"), and footprint-critical dimensions. No PCB layout changes are required.

Q: What is the significance of the product status difference between obsolete and active?

A: The 0872673250 is obsolete and no longer manufactured or distributed through standard channels. The 0877593250 is active, ensuring ongoing availability, technical support, and compliance with current regulatory requirements. For new production builds, the active substitute is the appropriate choice.

Q: How do the insulation material differences affect connector performance?

A: The original uses polyamide (PA) nylon insulation; the substitute uses thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements and are suitable for the specified automotive, general purpose, and telecommunications applications. Material selection reflects current manufacturing standards without degrading electrical or mechanical performance.

Q: Does the change from tin-lead to tin post finish impact solder joint reliability?

A: Both finishes are suitable for solder termination. Tin post finish in the 0877593250 aligns with lead-free soldering practices and RoHS3 compliance. Tin-lead finish in the original 0872673250 reflects legacy manufacturing. For new designs, the tin finish is the standard approach.

Q: What does the breakaway feature in the 0877593250 provide?

A: The breakaway capability allows individual connector sections to be separated if required for specific assembly or application needs. This feature does not affect compatibility with designs using the non-breakaway original part.

Q: Are there inventory or packaging differences between these parts?

A: The 0872673250 is listed with 729 pieces in stock (packaging not specified). The 0877593250 is available with 1666 pieces in tube packaging. Availability and packaging should be confirmed with the component distributor for procurement planning.

Q: What compliance certifications apply to both connectors?

A: Both connectors carry UL94 V-0 material flammability rating, MSL 1 (unlimited moisture sensitivity), REACH unaffected status, and EAR99 ECCN classification. The 0877593250 adds ROHS3 compliance, which the obsolete 0872673250 does not carry.
