RLR07C5101GSRE623 Equivalent & Substitute Parts

Part Overview

The RLR07C5101GSRE623 is a 5.1 kOhms ±2% 0.25W through-hole resistor manufactured by Vishay Dale, designed for military applications per MIL-PRF-39017/01 specification. This metal film axial resistor features moisture resistance and weldability, making it suitable for demanding environments requiring high reliability. The part is currently active in production with 849 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary packaging format (Tape & Reel) is unavailable or when inventory constraints require alternative distribution methods.

Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C5101GSRE623 is determined by strict equivalence across the following critical parameters:

• Resistance value: 5.1 kOhms
• Tolerance: ±2%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Package type: Axial
• Physical dimensions: 0.090" Dia x 0.250" L (2.29mm x 6.35mm)
• Military series compliance: MIL-PRF-39017/01, RLR07
• Failure rate: S (0.001%)

The identified substitute part RLR07C5101GSRE6 maintains identical electrical and mechanical specifications. The only difference is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both are manufactured by Vishay Dale and meet all military and reliability requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR07C5101GSRE623 and RLR07C5101GSRE6 are active products manufactured by Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability:

• RLR07C5101GSRE623 (Tape & Reel) is suitable for high-volume automated assembly processes requiring continuous reel feeding.
• RLR07C5101GSRE6 (Cut Tape) is suitable for lower-volume applications, manual assembly, or situations where reel-based packaging is not required.

Both parts comply with MIL-PRF-39017/01 military specifications and maintain the same failure rate classification. Neither part is RoHS compliant, and both are REACH affected. Selection should account for assembly equipment compatibility and procurement lead times, as the Cut Tape variant currently has higher inventory availability (1361 units versus 849 units).

Frequently Asked Questions (FAQ)

Q: Can RLR07C5101GSRE6 be used as a direct replacement for RLR07C5101GSRE623?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Reel). Direct substitution is valid provided your assembly process can accommodate Cut Tape packaging.

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

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place equipment. Cut Tape (CT) packaging supplies the same components on tape segments, typically used for lower-volume assembly or manual placement. Both formats contain identical components.

Q: Are there any electrical performance differences between the substitute parts?

A: No. Both parts have identical resistance (5.1 kOhms), tolerance (±2%), power rating (0.25W), temperature coefficient (±100ppm/°C), and operating temperature range (-65°C to 150°C).

Q: Do both parts meet military specifications?

A: Yes. Both RLR07C5101GSRE623 and RLR07C5101GSRE6 comply with MIL-PRF-39017/01 and are part of the RLR07 military series with S-class failure rate (0.001%).

Q: Which part should I select based on inventory?

A: RLR07C5101GSRE6 (Cut Tape) currently has higher inventory (1361 units) compared to RLR07C5101GSRE623 (Tape & Reel, 849 units). If inventory availability is a constraint, the Cut Tape variant may provide faster procurement, provided your assembly process supports this packaging format.
