Equivalent & Substitute Parts for 48BFSP1M2RT

Part Overview

The 48BFSP1M2RT is a slide switch manufactured by Grayhill Inc., classified as a Single Pole Double Throw (SPDT) switch with On-On functionality. This through-hole mounted component operates at 0.4VA across 20V AC/DC ratings and is designed for applications requiring reliable switching with gold-plated copper alloy contacts. The part is currently in active production status with 825 units in stock. Substitute parts are identified when equivalent electrical ratings, circuit configurations, and mechanical mounting specifications align with the original component, enabling direct replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 48BFSP1M2RT are identified based on strict alignment of the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-On
• Current rating must be 0.4VA (AC/DC)
• Voltage ratings must be 20V AC and 20V DC minimum

Mechanical Equivalence Criteria:

• Mounting type must be Through Hole
• Termination style must be PC Pin
• Contact material must be Copper Alloy with Gold finish

Compliance Criteria:

• RoHS3 compliance required for active substitution
• ECCN classification must be EAR99

Two substitute parts meet these criteria: 1825032-1 (TE Connectivity ALCOSWITCH Switches, Active status) and TSS11DGPC (TE Connectivity ALCOSWITCH Switches, Obsolete status). Both maintain identical electrical ratings and through-hole PC pin termination. Variations in actuator length, switch travel, mechanical life, and operating temperature ranges do not prevent substitution when electrical and mounting specifications are equivalent.

Engineering Selection Recommendations

Primary Substitute: 1825032-1

The 1825032-1 is the preferred substitute for the 48BFSP1M2RT. Both parts are ROHS3 compliant and maintain active product status. Electrical specifications are identical: 0.4VA at 20V AC/DC with SPDT On-On configuration. Mechanical mounting is equivalent with through-hole PC pin termination and gold-plated copper alloy contacts. The 1825032-1 features IP67 dust-tight and waterproof protection, providing enhanced environmental sealing compared to the epoxy sealed terminals of the original part. Operating temperature range is -20°C to 80°C, which is narrower than the 48BFSP1M2RT (-30°C to 85°C) but sufficient for most standard applications. Electrical life rating of 10,000 cycles is lower than the original 30,000 cycles; applications requiring extended cycle life should account for this difference.

Secondary Substitute: TSS11DGPC

The TSS11DGPC maintains electrical equivalence with identical 0.4VA at 20V AC/DC ratings and SPDT On-On switching function. Through-hole PC pin termination and gold-plated copper contacts ensure mechanical compatibility. However, this part carries obsolete product status and is not ROHS3 compliant. The TSS11DGPC offers superior mechanical life (60,000 cycles) and electrical life (60,000 cycles) compared to the original part, making it suitable for high-cycle applications where the original part may be unavailable. Use of this substitute should be limited to legacy system maintenance or applications where obsolete component status is acceptable.

Frequently Asked Questions (FAQ)

Q: Can 1825032-1 directly replace 48BFSP1M2RT in existing circuit boards?

A: Yes. Both parts share identical electrical ratings (0.4VA, 20V AC/DC, SPDT On-On), mounting type (through-hole), and termination style (PC pin). Physical dimensions vary slightly (actuator length 3.50mm vs. 3.10mm, switch travel 2.20mm vs. 3.05mm), but these differences do not prevent direct PCB substitution. Verify mechanical clearance in the specific application.

Q: What is the difference between the operating temperature ranges?

A: The 48BFSP1M2RT operates from -30°C to 85°C, while 1825032-1 operates from -20°C to 80°C. The original part has a wider temperature envelope. If the application requires operation below -20°C or above 80°C, the 1825032-1 is not suitable.

Q: Why is TSS11DGPC marked as obsolete?

A: TSS11DGPC carries obsolete product status from TE Connectivity ALCOSWITCH Switches. This designation indicates the manufacturer has discontinued active production and support. While the part remains electrically and mechanically equivalent, procurement may be limited to existing inventory. For new designs, 1825032-1 is the recommended active substitute.

Q: Does the difference in electrical life (30,000 vs. 10,000 cycles) affect substitution?

A: Electrical life ratings indicate expected switch durability under specified operating conditions. The 48BFSP1M2RT is rated for 30,000 cycles, while 1825032-1 is rated for 10,000 cycles. Applications with cycle counts below 10,000 are unaffected. Applications requiring 10,000 to 30,000 cycles should evaluate whether the lower rating of 1825032-1 meets reliability requirements.

Q: Are both substitute parts RoHS compliant?

A: 1825032-1 is ROHS3 compliant. TSS11DGPC carries "Not Applicable" RoHS status due to its obsolete designation. For applications requiring RoHS3 compliance, only 1825032-1 qualifies as a compliant substitute.

Q: What does the IP67 rating on 1825032-1 provide?

A: IP67 classification indicates dust-tight and waterproof protection. The 1825032-1 provides enhanced environmental sealing compared to the epoxy sealed terminals of the 48BFSP1M2RT, making it suitable for applications with moisture or dust exposure.

Q: Can TSS11DGPC be used in new product designs?

A: TSS11DGPC is not recommended for new designs due to obsolete product status and lack of RoHS3 compliance. Use 1825032-1 for new applications requiring an active, compliant substitute.
