Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 88948-902 is determined by the following critical parameters:

• Position Count & Pitch: 192 positions at 0.079" (2.00mm) pitch with 4-row configuration
• Connector Type & Mounting: Receptacle with female sockets, board edge mounting, through-hole, right-angle orientation
• Termination Method: Press-fit termination for PCB assembly
• Electrical Ratings: Voltage and current handling capacity
• Environmental Compliance: Flammability rating and operating temperature range

The TE Connectivity AMP Connectors 536511-4 meets the core mechanical and electrical substitution criteria, sharing identical position count, pitch, row configuration, mounting style, and termination method. Both connectors are rated UL94 V-0 and operate within overlapping temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 536511-4 serves as a functional substitute for the obsolete Amphenol ICC 88948-902 based on matching mechanical and electrical interface specifications. Both connectors share identical position counts, pitch spacing, row configuration, and mounting methodology, ensuring PCB layout compatibility.

The 536511-4 offers the advantage of active product status, providing ongoing manufacturer support and availability. The extended operating temperature range (-55°C ~ 125°C versus -55°C ~ 105°C) provides additional thermal margin for demanding applications.

Design consideration: The 536511-4 is rated for 30V operation compared to the 88948-902's 1000V rating. Applications requiring voltages exceeding 30V must evaluate alternative substitutes or retain the original part specification. Both connectors maintain UL94 V-0 flammability compliance and unlimited moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 536511-4 directly replace the Amphenol ICC 88948-902 in existing designs?

A: Mechanical and termination compatibility is confirmed. Electrical compatibility depends on application voltage requirements. The 536511-4 is rated for 30V maximum, while the 88948-902 supports 1000V. Verify your circuit voltage specifications before substitution.

Q: What are the key differences between these connectors?

A: The primary differences are product status (obsolete versus active), voltage rating (1000V versus 30V), operating temperature upper limit (105°C versus 125°C), and contact finish (not specified versus gold plating on the 536511-4). Mechanical interfaces and position counts are identical.

Q: Are both connectors RoHS compliant?

A: No. Both the 88948-902 and 536511-4 are classified as RoHS non-compliant. If RoHS compliance is required for your application, additional substitute evaluation is necessary.

Q: What does the 4-row, 192-position configuration mean for PCB layout?

A: The connector accommodates 192 signal or power connections arranged in 4 rows with 0.079" (2.00mm) spacing between adjacent contacts. This configuration is fixed for both connectors, ensuring identical footprint requirements on the printed circuit board.

Q: Can the 536511-4 handle the same current as the 88948-902?

A: The 88948-902 is rated for 1A per contact. The 536511-4 does not specify a current rating in the provided data. Contact the manufacturer for current handling specifications before substitution in high-current applications.
