Amphenol ICC 88948-102 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 88948-102 is a 192-position backplane connector receptacle with female sockets, designed for board edge mounting with through-hole, right-angle termination. This connector is part of the Metral® B series and features press-fit termination with gold-plated contacts rated for 1A at 1000V across an operating temperature range of -55°C to 105°C.

The 88948-102 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 88948-102 is determined by strict equivalence across the following critical parameters: connector type (receptacle, female sockets), number of positions (192), pitch (0.079" / 2.00mm), number of rows (4), mounting type (board edge, through-hole, right-angle), and termination method (press-fit). Contact finish, current rating, voltage rating, operating temperature range, and flammability rating must remain within acceptable tolerances for the application.

The substitute parts identified are grouped as follows:

Direct Equivalent (Same Manufacturer): 88948-102LF represents the active production variant of the same base product (88948) with identical electrical and mechanical specifications, differentiated only by packaging format and compliance status.

Cross-Manufacturer Alternative: TE Connectivity 536511-4 shares the core mechanical and electrical architecture (192 positions, 0.079" pitch, 4 rows, board edge mounting, press-fit termination) but operates under a different connector style designation (Futurebus, Z-PACK series) with modified electrical ratings and temperature range.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The 88948-102LF is the recommended substitute for the obsolete 88948-102. Both parts are manufactured by Amphenol ICC within the Metral® B series and maintain identical electrical and mechanical specifications. The 88948-102LF is in active production status with higher inventory availability (1402 pcs vs. 665 pcs). The primary distinction is RoHS compliance status: 88948-102LF is RoHS compliant, while the original 88948-102 is non-compliant. Selection of 88948-102LF is appropriate for applications requiring RoHS-compliant components or for new production designs.

For Cross-Manufacturer Substitution: The TE Connectivity 536511-4 provides mechanical and positional compatibility but introduces electrical specification differences that require application-level verification. The voltage rating is reduced from 1000V to 30V, and current rating is not specified. The operating temperature range extends to 125°C (versus 105°C for the Amphenol part). The 536511-4 is designated as Futurebus-style within the Z-PACK series. This part is suitable only for applications where the reduced voltage rating (30V) and unspecified current rating are acceptable within the system design envelope.

Frequently Asked Questions (FAQ)

Q: Can 88948-102LF be used as a direct replacement for 88948-102?

A: Yes. Both parts share identical connector type, position count (192), pitch (0.079" / 2.00mm), row configuration (4), mounting method (board edge, through-hole, right-angle), termination (press-fit), contact finish (gold), current rating (1A), voltage rating (1000V), operating temperature range (-55°C to 105°C), and flammability rating (UL94 V-0). The 88948-102LF is the active production equivalent and is recommended for new designs and legacy system maintenance.

Q: What are the key differences between 88948-102 and 88948-102LF?

A: The primary differences are product status (obsolete vs. active), packaging format (unspecified vs. tube), RoHS compliance (non-compliant vs. compliant), and REACH status (unaffected vs. affected). Electrical and mechanical specifications are identical.

Q: Is the TE Connectivity 536511-4 a suitable substitute?

A: The 536511-4 provides mechanical compatibility in terms of position count, pitch, row configuration, and mounting type. However, the voltage rating is significantly reduced (30V vs. 1000V), and current rating is not specified. This part is suitable only for applications where these electrical limitations are acceptable. Physical fit and connector interface must be verified for the specific application.

Q: What packaging options are available?

A: The 88948-102 original part does not specify packaging format. The 88948-102LF is supplied in tube packaging. The 536511-4 packaging format is not specified in the available data.

Q: Are there compliance considerations when selecting a substitute?

A: Yes. The 88948-102 is RoHS non-compliant and REACH unaffected. The 88948-102LF is RoHS compliant and REACH affected. The 536511-4 is RoHS non-compliant and REACH affected. Selection should align with the regulatory requirements of the target application and end-use market.
