Engineering Selection Recommendations

D38999/26MG41SN Selection: This substitute is recommended for applications requiring RoHS3 compliance. The part maintains full electrical and mechanical equivalence to the ACT96WG41SN while meeting enhanced environmental standards. Inventory availability of 1091 pieces supports production requirements. This variant is suitable for new designs or retrofit applications where regulatory compliance is mandatory.

D38999/26WG41SN Selection: This substitute provides the highest inventory availability at 30200 pieces, supporting immediate procurement needs and extended production schedules. The part maintains RoHS non-compliant status matching the original ACT96WG41SN, ensuring direct functional equivalence without compliance-driven design modifications. This variant is appropriate for legacy system maintenance, repair operations, and applications where RoHS compliance is not required.

Compliance Considerations: The D38999/26MG41SN variant introduces ROHS3 compliance and Not Applicable moisture sensitivity level, indicating design modifications for environmental standards. The D38999/26WG41SN maintains the original RoHS non-compliant status and MSL 1 rating, providing direct functional replacement without specification changes.

Inventory Strategy: Selection between D38999/26MG41SN and D38999/26WG41SN should prioritize application compliance requirements first, then inventory availability. The D38999/26WG41SN offers superior stock depth for time-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Are D38999/26MG41SN and D38999/26WG41SN directly interchangeable with ACT96WG41SN?

A: Both substitutes are mechanically and electrically equivalent to the ACT96WG41SN across all critical parameters: 41-position configuration, shell size G, crimp termination, threaded fastening, gold-plated contacts, and -65°C to 175°C operating range. The primary difference is RoHS compliance status. D38999/26MG41SN is ROHS3 compliant, while D38999/26WG41SN maintains RoHS non-compliant status matching the original part.

Q: What determines substitution eligibility for this 41-position circular connector?

A: Substitution eligibility is determined by equivalence across connector type (plug with female sockets), position count (41), shell size (G with 21-41 insert), termination method (crimp), fastening type (threaded), contact material and finish (gold-plated copper alloy), current rating (7.5A), temperature range (-65°C to 175°C), and shielding (shielded, environment-resistant). All listed substitutes meet these criteria.

Q: How does RoHS compliance affect part selection?

A: RoHS compliance is a regulatory requirement, not a functional specification. D38999/26MG41SN is ROHS3 compliant and suitable for applications subject to RoHS regulations. D38999/26WG41SN maintains RoHS non-compliant status, matching the original ACT96WG41SN, and is appropriate for legacy systems and applications without RoHS requirements. Functional performance is identical between compliant and non-compliant variants.

Q: What is the significance of moisture sensitivity level (MSL) differences?

A: The ACT96WG41SN and D38999/26WG41SN both carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. D38999/26MG41SN lists MSL as Not Applicable, reflecting its ROHS3 design modifications. For standard aerospace and military applications, MSL differences do not affect connector performance or compatibility.

Q: Which substitute offers the best inventory availability?

A: D38999/26WG41SN provides the highest inventory availability at 30200 pieces, compared to 1091 pieces for D38999/26MG41SN and 734 pieces for the discontinued ACT96WG41SN. For applications requiring immediate procurement or extended production runs, D38999/26WG41SN is the optimal choice.

Q: Are there any packaging differences between the main part and substitutes?

A: The ACT96WG41SN packaging information is not specified in available data. Both D38999/26MG41SN and D38999/26WG41SN are supplied in bulk packaging. Confirm packaging requirements with procurement specifications before finalizing part selection.

Q: Do all parts share the same export control classification?

A: Yes. The ACT96WG41SN, D38999/26MG41SN, and D38999/26WG41SN all carry EAR99 export control classification and identical HTSUS commodity code 8536.69.4020, ensuring consistent regulatory treatment across all substitutes.
