D44L-R1LD Equivalent & Substitute Parts Reference

Part Overview

The D44L-R1LD by ZF Electronics is a snap action SPDT switch, designed for chassis mounting and equipped with a straight lever actuator. It is rated for 10A at 125V AC and 6A at 30V DC, with an On-Mom switch function. Key features include quick-connect terminations, an operating temperature range of -40°C to 85°C, and compliance with ROHS3 and REACH standards. This part has been designated as obsolete, which necessitates the identification and selection of alternative models to ensure continued availability in current designs or maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection is strictly based on matching key parameters: circuit type (SPDT), switch function (On-Mom), current and voltage ratings, actuator type (lever, straight), mounting style (chassis), termination style, operating force, operating temperature range, and compliance certifications. Only parts with these matching parameters are listed as equivalents or substitutes. Package quantities and series designations are included for inventory management but do not affect direct substitution.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are ROHS-compliant and REACH-unaffected, supporting environmental compliance requirements. The main part (D44L-R1LD) is obsolete, while the substitute models (LS0851502F045C1A and V15H22-CZ300A02-K) are active and available in bulk or tray packaging, facilitating continued sourcing for manufacturing and service needs. ECCN and MSL levels are consistent across the parts, and all are suitable for unrestricted handling in standard production environments.

Frequently Asked Questions (FAQ)

Q1: What determines if a part is a valid substitute for D44L-R1LD?
A: A valid substitute must match circuit type (SPDT), switch function (On-Mom), actuator (lever, straight), mounting style (chassis), termination style, current and voltage ratings, operating force, temperature range, and be compliant with RoHS and REACH standards.

Q2: Are there differences in electrical ratings among substitutes?
A: Yes. Substitute parts may have higher current or voltage ratings than the original but must not have lower values than required for the application according to provided specifications.

Q3: What termination styles must be considered?
A: Termination style must match application requirements. D44L-R1LD uses quick connect - 0.187" (4.7mm); LS0851502F045C1A matches exactly, while V15H22-CZ300A02-K uses quick connect - 0.250" (6.3mm).

Q4: What are the implications of part status?
A: D44L-R1LD is obsolete; only active parts should be selected for ongoing manufacturing or design. Substitute parts listed are currently active.

Q5: Does the operating temperature range affect compatibility?
A: Substitutes must operate within the specified temperature range required for the application. All listed parts have at least overlapping temperature ranges as provided.

Q6: Are all substitute parts compliant with relevant environmental and trade regulations?
A: All listed substitute parts are RoHS compliant and REACH unaffected, with ECCN EAR99 and MSL 1 (unlimited), ensuring compatibility with industry regulations.
