88947-202 Equivalent & Substitute Parts Reference

Part Overview

The 88947-202 is a 96-position backplane connector receptacle manufactured by Amphenol ICC (FCI) in the Metral® B series. This board edge, through-hole, right-angle connector is designed for applications requiring press-fit termination with a 0.079" (2.00mm) pitch across 4 rows. The part is currently active in production with 846 units in stock.

Substitute parts become necessary when the main part reaches end-of-life status, when inventory constraints occur, or when design requirements shift to alternative connector architectures. The 88947-202 has one documented equivalent: the TE Connectivity 536511-3, which shares core mechanical and electrical compatibility parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 88947-202 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 96 positions at 0.079" (2.00mm) spacing
• Physical Configuration: 4-row board edge receptacle with right-angle, through-hole mounting
• Termination Method: Press-fit contact technology
• Electrical Ratings: Voltage and current handling capacity
• Environmental Compliance: Flammability rating (UL94 V-0) and temperature operating range

The TE Connectivity 536511-3 meets all core mechanical and electrical substitution criteria. However, differences in product status, contact finish, and voltage rating must be evaluated for specific application requirements.

Engineering Selection Recommendations

Primary Selection: 88947-202 (Amphenol ICC)

The 88947-202 remains the preferred choice for new designs and ongoing production. It is actively manufactured, carries a 1000V voltage rating suitable for high-voltage applications, and maintains full UL94 V-0 flammability compliance. Current inventory of 846 units supports immediate procurement.

Alternative Selection: 536511-3 (TE Connectivity)

The 536511-3 is mechanically and electrically compatible for applications where voltage requirements do not exceed 30V. This part is classified as obsolete, indicating limited future availability. The extended operating temperature range (-55°C ~ 125°C) provides thermal margin beyond the primary part. Gold contact finish offers enhanced corrosion resistance compared to unspecified contact treatment on the 88947-202. Selection of this substitute should be restricted to legacy system maintenance or applications with specific thermal or contact durability requirements where the reduced voltage rating is acceptable.

Both parts share identical mechanical configuration, pitch, position count, and press-fit termination, ensuring physical and functional interchangeability within their respective electrical rating constraints.

Frequently Asked Questions (FAQ)

Q: Can the 536511-3 be used as a direct replacement for the 88947-202 in all applications?

A: Physical and mechanical compatibility is confirmed. However, the 536511-3 voltage rating of 30V is significantly lower than the 88947-202 rating of 1000V. Substitution is only valid for applications operating at or below 30V. Verify your circuit voltage requirements before selection.

Q: What is the significance of the obsolete status for the 536511-3?

A: Obsolete status indicates the part is no longer in active production. While 1078 units are currently in stock, future availability cannot be guaranteed. For new designs or long-term production, the active 88947-202 is the recommended choice.

Q: Are there differences in contact reliability between these two parts?

A: The 536511-3 specifies gold contact finish, which provides enhanced corrosion resistance. The 88947-202 contact finish is not specified in available documentation. Both parts meet UL94 V-0 flammability requirements and share identical press-fit termination technology.

Q: Do both parts support the same operating temperature range?

A: No. The 88947-202 operates from -55°C to 105°C, while the 536511-3 extends to 125°C. For applications requiring operation above 105°C, the 536511-3 provides additional thermal margin, provided voltage requirements remain within its 30V limit.

Q: What packaging considerations apply to these connectors?

A: The 88947-202 is supplied in tube packaging. Packaging information for the 536511-3 is not specified. Confirm packaging requirements with your procurement process before finalizing orders.
