Equivalent & Substitute Parts for 48ASDP1S1V2RBT

Part Overview

The 48ASDP1S1V2RBT is a slide switch manufactured by Grayhill Inc., classified as a DPDT (Double Pole Double Throw) switch with a rated capacity of 0.4VA at 20V. This through-hole mounted component features gold-plated copper alloy contacts, polyamide actuator, and epoxy sealed terminals. The part is currently in active production status with 904 units available in inventory.

Equivalent and substitute parts are identified when design requirements permit operation within alternative electrical and mechanical parameter ranges, or when the primary part becomes unavailable due to supply constraints or obsolescence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 48ASDP1S1V2RBT is determined by the following critical parameters:

Circuit Configuration: DPDT topology is mandatory for functional equivalence.

Switch Function: On-On operation must be maintained.

Mounting and Termination: Through-hole mounting with PC pin termination is required for mechanical compatibility.

Electrical Ratings: Substitute parts must support the application's voltage and current requirements. A substitute with higher voltage and current ratings may be used in applications requiring 0.4VA at 20V, provided the physical form factor permits installation.

Operating Temperature Range: The -30°C to 85°C range establishes the minimum environmental specification.

Contact Timing: Non-shorting (BBM) contact timing is acceptable for On-On switches where break-before-make operation does not introduce functional constraints.

The identified substitute MS22BSW13 (NKK Switches) meets these criteria with elevated electrical specifications (6A at 125V AC), compatible mechanical dimensions (5.10mm actuator length, 2.20mm switch travel), and equivalent environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The 48ASDP1S1V2RBT remains the preferred choice for new designs. The part is in active production status with confirmed inventory availability (904 units), ensuring supply continuity and long-term support. RoHS compliance and MSL 1 rating provide regulatory alignment and simplified handling requirements.

Substitute Selection Criteria: The MS22BSW13 may be selected when the 48ASDP1S1V2RBT is unavailable and the application permits operation at elevated voltage and current specifications. The substitute's 6A/125V rating exceeds the primary part's 0.4VA/20V specification, making it suitable for applications with higher power requirements. However, the MS22BSW13 is classified as obsolete, indicating discontinued production and potential future supply constraints.

Compliance Considerations: Both parts maintain RoHS compliance and REACH unaffected status. The MS22BSW13 carries ROHS3 certification, which is compatible with ROHS compliant applications. MSL 1 rating on both parts eliminates moisture sensitivity concerns for standard storage and handling.

Mechanical Compatibility: Actuator length and switch travel dimensions are within 0.02mm tolerance across both parts, confirming mechanical interchangeability in standard through-hole PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can MS22BSW13 be used as a direct replacement for 48ASDP1S1V2RBT?

A: MS22BSW13 is electrically compatible for applications where the circuit operates at or below 0.4VA and 20V. The substitute's higher ratings (6A/125V) do not prevent operation at lower specifications. Mechanical dimensions are compatible. However, the obsolete status of MS22BSW13 makes it unsuitable for new designs requiring long-term supply assurance.

Q: What are the key differences between these two DPDT switches?

A: The primary differences are electrical ratings (0.4VA/20V versus 6A/125V), contact material (copper alloy with gold finish versus silver alloy with silver finish), actuator material (polyamide versus glass-filled PBT), electrical life (30,000 versus 25,000 cycles), and product status (active versus obsolete). Circuit configuration, switch function, mounting type, and operating temperature range are identical.

Q: Are the physical dimensions compatible for PCB mounting?

A: Yes. Actuator length differs by 0.02mm (5.08mm versus 5.10mm) and switch travel differs by 0.04mm (2.16mm versus 2.20mm). These variations are within standard PCB design tolerances and do not affect mounting compatibility.

Q: What does "Non-Shorting (BBM)" contact timing mean for the MS22BSW13?

A: BBM (Break-Before-Make) contact timing ensures that the switch breaks the previous connection before establishing the new connection. For On-On switches, this prevents momentary short circuits during actuation. The 48ASDP1S1V2RBT does not specify contact timing, but both configurations are functionally compatible for On-On applications.

Q: Why is MS22BSW13 listed as obsolete?

A: Obsolete status indicates that NKK Switches has discontinued production of this part. While existing inventory may be available through distributors, future supply cannot be guaranteed. New designs should prioritize the active 48ASDP1S1V2RBT to ensure long-term component availability.

Q: Are there compliance or certification differences between these parts?

A: Both parts are RoHS compliant and REACH unaffected. MS22BSW13 carries ROHS3 certification, which is a more recent RoHS standard revision. Both maintain MSL 1 rating, eliminating moisture sensitivity concerns. No compliance barriers exist for substitution.
