Equivalent & Substitute Parts for 5VTP 1.6-R

Part Overview

The 5VTP 1.6-R is a 1.6 A 250 V AC/DC fuse cartridge manufactured by Bel Fuse Inc. in a 5mm x 20mm glass through-hole package with slow-blow response characteristics. This part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system maintenance and new design implementations. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and functional performance to ensure direct compatibility in existing circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5VTP 1.6-R are qualified based on the following mandatory electrical and mechanical parameters:

• Current Rating: 1.6 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All identified substitute parts meet these criteria. Variations in melting I²t, DC cold resistance, physical dimensions within tolerance, and approval agency certifications do not disqualify substitution eligibility, as these parameters remain within acceptable operational ranges for the specified application category.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—021301.6MXEP, 021301.6MRET1P, and 021801.6MXEP—are active products from Littelfuse Inc. and meet the mandatory electrical and mechanical specifications of the obsolete 5VTP 1.6-R.

021301.6MXEP (Littelfuse Series 213, Bulk Packaging): This direct manufacturer equivalent maintains identical electrical characteristics and is available in bulk packaging. It carries comprehensive approval certifications including BSI, CCC, CE, CSA, PSE, SEMKO, UR, and VDE. This part is suitable for high-volume procurement and standard circuit protection applications.

021301.6MRET1P (Littelfuse Series 213, Tape & Reel Packaging): This part is electrically and mechanically identical to 021301.6MXEP but is supplied in tape and reel format. It is appropriate for automated assembly processes and production environments requiring component tape feeding systems.

021801.6MXEP (Littelfuse Series 218, Bulk Packaging): This part meets all mandatory electrical and mechanical requirements. It is available in bulk packaging and carries approval certifications including CCC, CE, CSA, K-MARK, PSE, SEMKO, UL, and VDE. The melting I²t value of 23.35 and DC cold resistance of 0.0336 Ohms differ from the original part, but these variations remain within acceptable operational parameters for the specified 1.6 A 250 V slow-blow cartridge fuse category.

Selection between these three options should be based on packaging requirements (bulk versus tape and reel) and specific certification needs for the target application.

Frequently Asked Questions (FAQ)

Q: Can 021301.6MXEP directly replace 5VTP 1.6-R in existing designs?

A: Yes. The 021301.6MXEP maintains identical current rating (1.6 A), voltage rating (250 V AC), fuse type (cartridge glass), response time (slow blow), package dimensions (5mm x 20mm axial), mounting type (through hole), and breaking capacity (35 A). It is a direct electrical and mechanical equivalent.

Q: What is the difference between 021301.6MXEP and 021301.6MRET1P?

A: Both parts are electrically and mechanically identical. The primary difference is packaging: 021301.6MXEP is supplied in bulk, while 021301.6MRET1P is supplied in tape and reel format. Selection depends on assembly process requirements.

Q: Can 021801.6MXEP be used as a substitute for 5VTP 1.6-R?

A: Yes. The 021801.6MXEP meets all mandatory electrical and mechanical specifications. The melting I²t (23.35) and DC cold resistance (0.0336 Ohms) differ from the original part, but these variations do not affect substitution eligibility for the specified 1.6 A 250 V slow-blow fuse application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts—021301.6MXEP, 021301.6MRET1P, and 021801.6MXEP—are ROHS3 compliant and REACH unaffected.

Q: Which substitute part has the broadest approval certifications?

A: The 021301.6MXEP and 021301.6MRET1P both carry seven approval certifications (BSI, CCC, CE, CSA, PSE, SEMKO, UR, VDE). The 021801.6MXEP carries eight certifications (CCC, CE, CSA, K-MARK, PSE, SEMKO, UL, VDE). Selection should align with specific regional or application-specific certification requirements.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts operate within the range of -55°C to 125°C, matching the original 5VTP 1.6-R specification.
