Key Parameters

Substitute Part Grouping Explanation

The RN70E2500BB14 qualifies as a direct substitute for the RN70C2500BRE6 based on the following critical parameters:

• Identical resistance value: 250 Ohms
• Identical tolerance: ±0.1%
• Identical power rating: 0.75W (3/4W)
• Identical composition: Metal Film
• Identical package type: Axial
• Identical physical dimensions: 0.180" Dia x 0.562" L (4.57mm x 14.27mm)
• Identical operating temperature range: -65°C ~ 175°C
• Identical series classification: Military, MIL-R-10509/3, RN70
• Identical product status: Active

The primary difference between these parts is packaging format (Tape & Reel versus Bulk) and temperature coefficient specification (±50ppm/°C versus ±25ppm/°C). Both parts maintain full electrical and mechanical compatibility for direct substitution in applications requiring 250 Ohm military-grade metal film resistors.

Parameter Comparison

Engineering Selection Recommendations

Both RN70C2500BRE6 and RN70E2500BB14 are active production parts from Vishay Dale within the military-grade RN70 series. Selection between these parts should be based on:

Packaging requirements: RN70C2500BRE6 is supplied in Tape & Reel format suitable for automated assembly processes. RN70E2500BB14 is supplied in Bulk format suitable for manual assembly or smaller quantity applications.

Temperature coefficient specification: RN70E2500BB14 provides a tighter temperature coefficient (±25ppm/°C) compared to RN70C2500BRE6 (±50ppm/°C). Applications requiring superior temperature stability should specify RN70E2500BB14.

Inventory availability: RN70E2500BB14 has higher stock availability (2250 pieces) compared to RN70C2500BRE6 (1096 pieces).

Both parts maintain identical compliance status (RoHS non-compliant, REACH Affected, ECCN EAR99) and are suitable for military applications requiring MIL-R-10509/3 conformance.

Frequently Asked Questions (FAQ)

Q: Can RN70E2500BB14 be used as a direct replacement for RN70C2500BRE6?

A: Yes. Both parts are electrically and mechanically identical with respect to resistance value, tolerance, power rating, physical dimensions, and operating temperature range. The primary difference is packaging format (Tape & Reel versus Bulk) and temperature coefficient specification.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel packaging (RN70C2500BRE6) is designed for automated pick-and-place assembly equipment and is standard for high-volume production. Bulk packaging (RN70E2500BB14) consists of loose components suitable for manual assembly or lower-volume applications.

Q: Does the tighter temperature coefficient of RN70E2500BB14 affect compatibility?

A: No. The ±25ppm/°C temperature coefficient of RN70E2500BB14 is a superior specification compared to the ±50ppm/°C of RN70C2500BRE6. Applications designed for either part will function correctly with RN70E2500BB14, with improved temperature stability.

Q: Are both parts suitable for military applications?

A: Yes. Both RN70C2500BRE6 and RN70E2500BB14 conform to MIL-R-10509/3 specifications and are classified as military-grade components with flame retardant coating and moisture resistance.

Q: What compliance certifications apply to these parts?

A: Both parts are RoHS non-compliant, REACH Affected, and classified under ECCN EAR99 with HTSUS code 8533.21.0090.
