Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MVM5JB1K00 is determined by the following critical parameters:

• Resistance value: 1 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package configuration: Radial through-hole (exact match required)
• Number of terminations: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

The substitute part TWM5J1K0E manufactured by Ohmite meets all critical electrical and mechanical parameters. Variations in temperature coefficient, maximum operating temperature, and physical dimensions within acceptable tolerances do not preclude substitution when the core functional specifications align.

Parameter Comparison

Engineering Selection Recommendations

Both the MVM5JB1K00 and TWM5J1K0E are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application-specific requirements:

The MVM5JB1K00 is suitable for standard applications within the -55°C to 155°C operating range with moisture-resistant construction. The TWM5J1K0E offers extended temperature capability to 275°C and higher temperature coefficient tolerance, making it applicable to more demanding thermal environments. Both parts maintain identical electrical performance at rated specifications and are mechanically compatible in radial through-hole circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can TWM5J1K0E replace MVM5JB1K00 in existing designs?

A: Yes. Both parts share identical resistance, tolerance, power rating, composition, and package configuration. The TWM5J1K0E features extended operating temperature range and higher temperature coefficient, which do not prevent substitution in applications designed for the MVM5JB1K00 specifications.

Q: What are the physical dimension differences?

A: The MVM5JB1K00 measures 0.512" L x 0.374" W (13.00mm x 9.50mm), while the TWM5J1K0E measures 0.492" L x 0.354" W (12.50mm x 9.00mm). Both have identical seated height of 1.024" (26.00mm). These minor dimensional variations are within acceptable tolerances for standard radial through-hole mounting.

Q: Are there packaging differences?

A: The MVM5JB1K00 is supplied in Tray packaging, while the TWM5J1K0E is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: What is the significance of temperature coefficient differences?

A: The MVM5JB1K00 has a temperature coefficient of ±200ppm/°C, while the TWM5J1K0E has ±350ppm/°C. This means the TWM5J1K0E exhibits greater resistance variation across temperature extremes. For applications with tight tolerance requirements across wide temperature ranges, the MVM5JB1K00 may be preferred.

Q: Which part should be selected for high-temperature applications?

A: The TWM5J1K0E supports operating temperatures up to 275°C compared to 155°C for the MVM5JB1K00. For applications exceeding 155°C, the TWM5J1K0E is the appropriate selection.
