RR1220P-2553-D-M Equivalent & Substitute Parts

Part Overview

The RR1220P-2553-D-M is a 255 kOhms ±0.5% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This surface-mount device is rated for 0.1W (1/10W) power dissipation and operates across the temperature range of -55°C to 125°C. The component is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and carries Active product status. Substitute parts are identified when equivalent resistance values, package formats, and electrical specifications align with application requirements while offering alternative tolerance grades, power ratings, or enhanced certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RR1220P-2553-D-M is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 255 kOhms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Number of terminations: 2 (exact match required)

Allowable Variation Parameters:

• Tolerance: May be equal to or tighter than ±0.5%
• Power rating: Must be equal to or greater than 0.1W
• Operating temperature range: Must encompass or extend the -55°C to 125°C range
• Temperature coefficient: May differ within thin film specifications
• Packaging format: Tape & Reel or Strip acceptable for equivalent functionality

All substitute parts listed maintain ROHS3 compliance and MSL 1 rating. Substitute parts are grouped by tolerance grade and power rating characteristics while maintaining identical resistance and package specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Equivalent Functionality):

The three substitute parts listed are functionally equivalent to the RR1220P-2553-D-M for applications requiring 255 kOhms resistance in 0805 package format. All substitute parts maintain Active product status and ROHS3 compliance.

3-2176094-2 (TE Connectivity): This substitute offers tighter tolerance (±0.1% versus ±0.5%) and higher power rating (0.25W versus 0.1W). Operating temperature range extends to 155°C. Height-seated dimension increases to 0.026" (0.65mm). Suitable for applications requiring enhanced precision and thermal headroom.

RP73D2A255KBTG (TE Connectivity): This substitute provides tighter tolerance (±0.1%) and improved temperature coefficient (±15ppm/°C versus ±25ppm/°C). Power rating is 0.125W (1/8W). Operating temperature range extends to 155°C. Height-seated dimension is 0.026" (0.65mm). Supplied in Strip packaging rather than Tape & Reel.

ERA-6AEB2553V (Panasonic): This substitute includes Automotive AEC-Q200 certification, indicating qualification for automotive applications. Tolerance is ±0.1%, power rating is 0.125W (1/8W), and operating temperature range extends to 155°C. Height-seated dimension is 0.024" (0.60mm). REACH status is REACH Unaffected.

All substitute parts are electrically compatible with the main part specification. Selection should be based on application-specific requirements for tolerance grade, power dissipation margin, temperature operating range, and any automotive or specialized certifications required.

Frequently Asked Questions (FAQ)

Q: Can the 3-2176094-2 be used as a direct replacement for the RR1220P-2553-D-M?

A: Yes. Both components share identical 255 kOhms resistance, 0805 package format, and thin film composition. The 3-2176094-2 offers tighter tolerance (±0.1%) and higher power rating (0.25W). The increased height-seated dimension (0.026" versus 0.020") must be verified against PCB layout constraints.

Q: What is the primary difference between RP73D2A255KBTG and ERA-6AEB2553V?

A: Both parts provide 255 kOhms ±0.1% in 0805 package with 0.125W power rating. The ERA-6AEB2553V includes Automotive AEC-Q200 certification and has a lower height-seated dimension (0.024" versus 0.026"). The RP73D2A255KBTG offers a lower temperature coefficient (±15ppm/°C versus ±25ppm/°C).

Q: Are there packaging differences between substitute parts?

A: Yes. The RR1220P-2553-D-M and 3-2176094-2 are supplied in Tape & Reel (TR) packaging. The RP73D2A255KBTG is supplied in Strip packaging. ERA-6AEB2553V is supplied in Tape & Reel (TR). Packaging format affects handling, storage, and automated assembly processes.

Q: Do all substitute parts support the same operating temperature range as the main part?

A: No. The RR1220P-2553-D-M operates from -55°C to 125°C. All three substitute parts extend the upper limit to 155°C, providing additional thermal margin. Applications limited to 125°C maximum will operate within specification with any substitute part.

Q: Which substitute part has the best temperature stability?

A: The RP73D2A255KBTG offers the lowest temperature coefficient at ±15ppm/°C, compared to ±25ppm/°C for the main part and other substitutes. This provides superior frequency stability and reduced drift over temperature variations.

Q: Is the RR1220P-2553-D-M suitable for automotive applications?

A: The RR1220P-2553-D-M does not carry automotive certification. For automotive applications requiring AEC-Q200 qualification, the ERA-6AEB2553V is the appropriate selection among the listed substitutes.

Q: Can the higher power-rated 3-2176094-2 (0.25W) be used in place of the 0.1W main part?

A: Yes. A higher power rating provides additional thermal margin and does not degrade performance in applications designed for lower power dissipation. The 3-2176094-2 is electrically and mechanically compatible with the RR1220P-2553-D-M footprint, subject to height clearance verification.
