88951-905 Equivalent & Substitute Parts

Part Overview

The 88951-905 is a 24-position backplane connector header manufactured by Amphenol ICC (FCI) as part of the Metral® series. This through-hole solder-terminated connector is designed for high-speed applications with male pins and a 0.079" (2.00mm) pitch in a 4-row configuration. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 88951-905 is determined by the following critical parameters that must remain consistent:

• Connector Position Count: 24 positions (non-negotiable for mating compatibility)
• Pitch Specification: 0.079" (2.00mm) (determines PCB layout and mating interface)
• Row Configuration: 4 rows (physical form factor requirement)
• Connector Type: Header with male pins (functional interface requirement)
• Mounting Method: Through hole solder termination (assembly process compatibility)
• Operating Temperature Range: -55°C ~ 125°C (environmental specification)
• Flammability Rating: UL94 V-0 (material safety requirement)

The substitute part 5536501-1 maintains all these critical parameters, enabling direct functional replacement in applications where the 88951-905 is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The 5536501-1 (TE Connectivity AMP Connectors, Z-PACK series) is the designated substitute for the obsolete 88951-905. This substitution is based on:

Mechanical Compatibility: Both connectors share identical position count (24), pitch (0.079"/2.00mm), row configuration (4), and mounting method (through-hole solder termination), ensuring direct PCB layout compatibility without redesign.

Environmental Specifications: Both parts maintain the same operating temperature range (-55°C ~ 125°C) and UL94 V-0 flammability rating, meeting equivalent environmental and safety requirements.

Product Availability: The 5536501-1 is currently in active production status with substantial inventory availability (2162 pcs), whereas the 88951-905 is obsolete. For new designs or system maintenance requiring this connector form factor, the 5536501-1 provides assured long-term supply.

Compliance Consideration: The 5536501-1 is RoHS compliant, whereas the 88951-905 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulations or customer requirements mandating compliant components.

Frequently Asked Questions (FAQ)

Q: Can the 5536501-1 be used as a direct replacement for the 88951-905 in existing designs?

A: Yes. Both connectors maintain identical mechanical and electrical specifications for the critical parameters: 24 positions, 0.079" (2.00mm) pitch, 4-row configuration, through-hole solder termination, and operating temperature range. No PCB redesign is required.

Q: What are the differences between these two connectors?

A: The primary differences are manufacturer (Amphenol ICC vs. TE Connectivity), series designation (Metral® vs. Z-PACK), product status (obsolete vs. active), and RoHS compliance status. The 5536501-1 includes gold contact finish (30.0µin/0.76µm) and specifies 30V voltage rating, whereas the 88951-905 does not provide these specifications in the available data.

Q: Is the 5536501-1 available in the same packaging as the 88951-905?

A: The 5536501-1 is supplied in tube packaging. Packaging specifications for the 88951-905 are not provided in the available data. Confirm packaging requirements with your procurement or assembly process specifications.

Q: Are there any current rating differences between these connectors?

A: The 88951-905 specifies a 1A current rating. The 5536501-1 does not provide a current rating specification in the available data. Verify current requirements for your application and confirm compatibility with the substitute part's electrical characteristics.

Q: Should RoHS compliance status influence the selection decision?

A: RoHS compliance is relevant only if your application, customer requirements, or regulatory jurisdiction mandate RoHS-compliant components. The 5536501-1 is RoHS compliant, while the 88951-905 is not. For applications without RoHS requirements, this difference is not a technical constraint.
