Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SBR-EV-29-P-ML is determined by the following critical parameters:

• Connector type and style (SAS receptacle)
• Position count (29 positions)
• Through-hole mounting capability
• Gold contact finish with matching thickness specification
• RoHS and MSL compliance equivalence

The substitute part 10045782-001LF meets these core requirements. The primary difference between the main part and substitute is the termination method: the original uses solder termination, while the substitute employs press-fit termination with board guide features. Both termination methods are valid for through-hole PCB mounting and provide equivalent electrical connectivity for SAS applications.

Parameter Comparison

Engineering Selection Recommendations

The 10045782-001LF serves as the active substitute for the obsolete SBR-EV-29-P-ML. Both parts maintain identical electrical specifications, contact finish properties, and compliance certifications. The substitute is currently in active production status with higher inventory availability (4917 pcs vs. 1225 pcs), supporting long-term supply chain continuity.

Selection between solder and press-fit termination should be based on existing PCB design and assembly process requirements. Press-fit termination offers improved reliability in high-reliability applications and eliminates solder joint variables. Solder termination remains viable where existing assembly infrastructure and design specifications mandate this approach.

Frequently Asked Questions (FAQ)

Q: Can the 10045782-001LF directly replace the SBR-EV-29-P-ML in existing designs?

A: Yes, provided the PCB design accommodates press-fit termination holes. Both connectors share identical position counts, mounting type, and electrical specifications. PCB hole diameter and depth requirements differ between solder and press-fit termination methods and must be verified against the respective connector datasheets.

Q: What is the primary advantage of press-fit termination over solder termination?

A: Press-fit termination eliminates solder joint formation variables and provides consistent contact pressure through mechanical retention. This method is preferred in applications requiring high reliability and repeatability.

Q: Are both parts suitable for new designs?

A: The 10045782-001LF is recommended for new designs due to its active product status and higher inventory availability. The SBR-EV-29-P-ML is obsolete and should be used only for legacy system support or replacement applications.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry MSL 1 (Unlimited) rating, and share identical ECCN and HTSUS classifications.

Q: What is the board guide feature on the substitute part?

A: The board guide is a mechanical feature that aids in connector alignment during PCB assembly and press-fit insertion, improving assembly process reliability.
