Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0877153908 is determined by strict equivalence across the following critical parameters:

• Card Type & Electrical Interface: PCI Express™ standard compliance
• Physical Dimensions: 230-position configuration, 0.039" (1.00mm) pitch, 0.062" (1.57mm) card thickness
• Contact Specifications: Phosphor bronze material with gold plating (15.0µin thickness)
• Termination Method: Solder, staggered through-hole mounting
• Insulation Composition: Polyamide (PA46) glass-filled nylon
• Compliance Standards: ROHS3 compliance and MSL 1 rating

The substitute part 0877153909 meets all these parameters identically, differing only in product status (active vs. obsolete) and packaging configuration (tray vs. bulk).

Parameter Comparison

Engineering Selection Recommendations

The Molex 0877153909 is the direct functional equivalent to the 0877153908. Both parts maintain identical electrical and mechanical specifications for PCI Express card edge connector applications. The primary distinction is product lifecycle status: the 0877153908 is obsolete, while the 0877153909 is active and currently manufactured.

For new designs and ongoing system support, the 0877153909 is the appropriate selection. Both parts carry ROHS3 compliance and MSL 1 ratings, ensuring compatibility with modern manufacturing and storage requirements. The packaging difference (tray vs. bulk) does not affect electrical or mechanical performance and is determined by procurement volume and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 0877153909 be used as a direct replacement for the 0877153908 in existing designs?

A: Yes. The 0877153909 is electrically and mechanically identical to the 0877153908. All contact specifications, pitch, position count, termination method, and insulation materials are equivalent. The connector will function identically in PCI Express applications.

Q: What is the difference between the two part numbers?

A: The 0877153908 is classified as obsolete, while the 0877153909 is an active product. The packaging differs (bulk vs. tray), but this does not affect connector performance. The 0877153909 is the current production equivalent.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant with MSL 1 ratings. Compliance certifications are identical.

Q: Does packaging affect connector compatibility?

A: No. Packaging (tray vs. bulk) is a logistics consideration only and does not impact electrical or mechanical performance. The connector itself is identical.

Q: What parameters must match for a valid substitute?

A: For PCI Express card edge connectors, critical matching parameters include: card type, position count, pitch, card thickness, contact material and finish, termination method, mounting type, and insulation material. All these parameters are identical between the 0877153908 and 0877153909.
