MP2-S090-51M1-C-LR Equivalent & Substitute Parts

Part Overview

The MP2-S090-51M1-C-LR is a 90-position Futurebus+® backplane connector receptacle manufactured by 3M under the MetPak™ MP2 series. This board edge, through-hole mounted connector features female sockets with right-angle orientation and solder termination, designed for high-density backplane applications. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and legacy equipment support.

Substitute Part Grouping Explanation

Substitution for the MP2-S090-51M1-C-LR is determined by strict alignment of the following critical parameters:

Connector Type & Style: Receptacle with female sockets in Futurebus configuration
Position Count & Pitch: 90 positions at 0.079" (2.00mm) pitch
Row Configuration: 5-row arrangement
Mounting & Termination: Board edge, through-hole, right-angle orientation with solder termination
Environmental Compliance: UL94 V-0 flammability rating, RoHS compliance, and MSL 1 rating
Operating Temperature: -55°C ~ 125°C range

The substitute parts 223004-3 and 5223004-3 from TE Connectivity AMP Connectors meet all critical substitution criteria. Both are manufactured under the Z-PACK series and maintain functional equivalence through identical position count, pitch, row configuration, mounting style, and environmental specifications. The primary distinction between substitutes is packaging format (Bulk vs. Tube).

Engineering Selection Recommendations

Both TE Connectivity substitute parts (223004-3 and 5223004-3) are functionally equivalent to the obsolete MP2-S090-51M1-C-LR and maintain active product status with full RoHS compliance. Selection between the two substitutes should be based on packaging requirements:

223004-3: Bulk packaging format, suitable for high-volume assembly operations or inventory consolidation
5223004-3: Tube packaging format, appropriate for controlled dispensing environments or smaller batch requirements

Both substitutes satisfy all electrical, mechanical, and environmental specifications required for direct replacement in legacy Futurebus+® backplane applications. The transition from the obsolete 3M MetPak™ MP2 series to the active TE Connectivity Z-PACK series maintains full compatibility with existing board designs and connector mating interfaces.

Frequently Asked Questions (FAQ)

Q: Can 223004-3 and 5223004-3 be used interchangeably with MP2-S090-51M1-C-LR?

A: Yes. Both TE Connectivity parts are functionally equivalent substitutes. They share identical electrical and mechanical specifications including 90-position count, 0.079" pitch, 5-row configuration, board edge through-hole mounting, and solder termination. The only difference is packaging format (Bulk vs. Tube).

Q: What is the primary reason for substitution?

A: The MP2-S090-51M1-C-LR is classified as obsolete. The TE Connectivity alternatives (223004-3 and 5223004-3) are active products with ongoing manufacturing and supply availability, ensuring long-term component sourcing for maintenance and repair applications.

Q: Are there differences in contact finish specifications?

A: The main part specifies 3.00µin (0.076µm) gold contact finish thickness. The 223004-3 specifies 30.0µin (0.76µm), which is thicker and provides enhanced durability. The 5223004-3 does not specify contact finish thickness in available data. Both maintain gold contact finish material.

Q: Do the substitutes meet the same environmental and compliance standards?

A: Yes. All three parts are UL94 V-0 rated, RoHS compliant, and rated for MSL 1 (Unlimited moisture sensitivity). Operating temperature range is identical at -55°C ~ 125°C across all parts.

Q: What packaging considerations should guide part selection?

A: Choose 223004-3 (Bulk) for high-volume assembly lines or when consolidating inventory into standard reels. Choose 5223004-3 (Tube) for controlled dispensing in smaller batch operations or when tube packaging integrates with existing assembly automation.

Q: Are there voltage or current rating differences?

A: The main part specifies 1.5A current rating. The TE Connectivity substitutes do not specify current rating in available data. The 223004-3 specifies 30V voltage rating; the main part and 5223004-3 do not specify voltage rating in available data. Consult detailed datasheets for complete electrical specifications when voltage or current ratings are critical to application requirements.
